[A brief history and a few remarks about classifications of aneurysmal subarachnoid hemorrhages and scales of follow-up]

Abstract

A brief history of the most current scales of aneurysmal subarachnoid hemorrhage and follow-up is presented. Advantages and inaccuracies of these scales are discussed. The World Federation of Neurological Surgeons (WFNS) classification is recommended as the most objective and reliable although some critics exist about its use in particular conditions. The grading of the follow-up is also analyzed. Here, the Glasgow Outcome Scale (GOS) is the most common employed and promoted in a first approach in spite of its briefness. Secondary functional and neuropsychological examination at 6 or 12 months is to be recommended to enable a more accurate evaluation. In conclusion, the WFNS scales for subarachnoid hemorrhage and follow-up is proposed as the best way to allow comparison between work of different centers.
